Specification of Letters Patent. Patented Sept. 21,1915,

Original application filed April 9, 1914, Serial No. 830,744. Divided and this application filed November 3,

, .1914. Serial No. 870,071.

as dumping cars, such asare used, for in v stance, 1n railroad construction, for conveymg ballast, filling material, and the like to such places as the same may be needed, and dumping the same upon or at the side of the right of way, and for other similar uses; and has for its object to provide such a car which shall be simple in construction and easy of operation,"and which shall be pro-' vided with means for tilting the same oleerated by compressed air or similar power, and with means for elevating the side of the car as the car is tilted, in order that the contents of the same may be allowedtoescape; thisapplication being a division of my copending application, filed April 9, 1914, and bearing the Serial N 0. 830,744..

The invention consists in the novel construction, arrangement and combination of various devices, elements and parts as shown in the accompanying drawings, and hereinafter more particularly described.

In the said drawings, Figure 1 is a transverse sectional view of my improved dumping car, showing the same in its horizontal or carrying position; and Fig. 2 is a transverse sectional view showing the car in its tilted or dumping position,'with one sidewall elevated to allow the'escape of the contents, ashereinafter described.

In carrying my invention into effect I provide for the lower part of the car a running gear of the common or any suitable form of construction, comprising suitable sills,-and bolsters whichl have numbered ,12 in the drawings, which are mounted on two I bogie trucks, provided with journal boxes 13 forming the bearings forthe ends 1 of the axles of the wheels 14.

The upper or carrying portion of the car is suitably pivotally supported over the running gear above referred to. The method of supporting shown in the accompanying drawings will be hereinafter de- 5 Scribed, but is not claimed herein, being claimed in a co-pending application. This carrymg portion comprises a floor 15, to

the under side of which are secured spreader plates 16, which are trunnioned in bearing plates 17. The floor is provided with ends 51, {and sides 17 and 48, the latter being capable of being elevated for discharging the load, as hereinafter described. The spreader plates 16 are, provided with'trunnions19, bearing in openings 18 in bearing plates 17. WVhen the car is in its normal carrying position, as shown in Fig. 1, it is held by the toggles comprising the members 37 and 39, and by the chains 60 and 61, which pass downward around the pulleys 62 and 63, and are suitablysecured at the end of the car.

" When it is desired to tilt the car for the purpose of dumping the loadthe chains 60and 61 are suitably released, and the togpower, and these pipes are of course vsupplied with the necessary valves and, with means for operating the same. This cylinder is provided with a piston 55 of the usual construction, the rod 23 of which is prolonged and provided with a rack 53. This rack gears with a pinion 52 secured to a shaft to which is secured a pinion or gear 21 which engages with a geared rack 20 "secured to the tilting body of the car. The

pinion 52 may, of course, if desired gear directly with the rack 20. When air is admitted into the cylinder 56 on one side or the other of the piston as the case may be, it is evident that the said piston and the rod 23 will be moved and the car body tilted. When thecar body is tilted, it is vof course necessary, in order to discharge the load, that the-side wall of the lower half of the car shall be opened to permit the escape of itscontents. This is effected automatically bythe following described mechafnism: The sides 17 and 48 are provided at each end with extensions 90, which are located outside of the ends 86 of the car body and are provided with studs 89 which when the sides are lowered or closed rest; in notches 80 in the end frames 91 of the car and in the ends 86 of the body. Secured to r the ends 51 of the body are rollers 85. The

,dles of such extensions are supported by the pivots or studs 89 resting in the end frames 91, the outerends,bearingtlie sides a: are elevated, as shown in said figure. When the side wall is entirely raised the'inner end of the extension 90 on that'side of the'car bears against a block 86. If the body be only partially tilted, of course only a partial elevation of the side occurs, but still enough. to permit of the discharge of the contents of the car. I

The'operation and advantages of my invention will be obvious from what has been above said[ i V I Having thus described my invention, what I claimas new and desire to secure by Let- 'ters Patent is as follows:

. running gear, end frames, means adapted to pivotally support said body upon said running gear, and means adapted when in one position to maintain said body horizontal and when in another position to allow said body to tilt; of means adapted to tilt the said body, and means adapted to elevate a side wall of the said body as the same is tilted, said means comprising an extension on said side wall fulcrumed in one of said end frames, and means adapted to depress the inner end of said extension, the point of engagement betweenthe said depressing means and the said extension moving along said extension as the body is tilted.

2. In a dumping car, the combination with running gear, end frames, a car body pivotally supported upon said running gear and between said end frames, and sides for said car body provided with extensions pivotally mounted in said end frames, of means adapted to tilt said body from its horizontal position and means adapted to elevate one of said sides as the car body tilts, comprising a roller upon the end of the car body adapted to bear upon the'inner ends of the said extensions of said sides and to depress said inner ends and thereby elevate the outer ends bearing the sides.

8. In a dumping car, the combination with running gear, end, frames, one of said end frames being provided with notches, a car body pivotally supported upon said running tilts, comprising a device upon the endof gear andbetween the said end frames, and s des for sald car body, said sldes being provided with extensions having studs adapted to pivotally engage with the said extensions and to depress said inner ends and thereby elevate the outer ends bearing the'sides,

4-. In a dumping car, the combination with running gear, .end frames, each of said end frames being provided with a notch, a car body pivotally supported upon said running gear and between the said end frames,

and sides for said car body, said sides being 7 provided with studs ada ited to pivotally engage with the notches in said end frames;

of means adapted to tilt said body from its horizontal position and means adapted to elevate one of said sides as the car body.

9o the car body adapted to bear upon the inner ends of the said extensions and to depress said inner ends and thereby elevate the outer ends bearing the sides. 1

5. In a dumping car, the combination with running gear, end frames, one of said end frames being provided with notches, a car body pivotally supported upon said run ninggear and between the said end frames, and sides for said car body, said sides being provided with extensions having studs adapted to pivotally en age with the said notches'in-said end frame; of means adapted to tilt said body from its horizontal posi-.. tion, means adapted to elevate one of said sides as the car body tilts, comprising a device upon the end of the car body adapted to bear upon the inner ends of "the said extensions and to depress said inner ends and w thereby elevate the outer ends bearing the sides, and supports against which the inner ends of said extensions are adapted to hear when said side walls are elevated.
